A projectile is launched from a point on level ground with initial speed 21 miles/hour and initial angle of 38.9 degrees above the horizontal. Air resistance may be ignored and normal earth gravity is present. Calculate the final value of the vertical component of velocity in m/s just prior to the projectile striking the ground. [Note: A positive answer denotes up and a negative answer denotes down. Don't forget to convert units as needed.]
